That gives sample A a protein concentration of Since these concentrations are not near any of the concentrations on the list, we resort to other methods to determine what the unknown substances were. From qualitative observation, we noticed that sample A was a white color, while sample B was a tan color.
This activity will allow students to evaluate two patients with possible neurological symptoms. Students will come up with possible diagnosis and determine how to test for these diagnoses. A patient and his wife come in to see you with a concern. The patient has a history of sickle cell disease in his family, but neither of his parents have exhibited any symptoms.
The wife is an immigrant from rural tropical Africa and has no idea if her family has any history of sickle cell disease. However the area she is from has a high incidence of sickle cell anemia in the population.
The couple has 2 children, ages 4, 8 and would like to have another. The couple has come to you for advice on whether or not to have another child, and what to tell their children about the family medical history.
How is DNA analyzed and manipulated using restriction enzymes? Students compare the DNA fragments with the known restriction map of bacteria phage lambda. This activity demonstrates how DNA sequences can be mapped and characterized, such as in the Human Genome Project and how DNA is cut and arranged during genetic engineering.
What is genetic engineering, and how is this technique used? Students perform a genetic engineering experiment using bacterial transformation to introduce fluorescent genes into Escherichia coli E. This activity helps students understand what genes do and how they can be manipulated by genetic engineering.
This activity will confirm that different genes introduced by transformation will result in different visible characteristics. This activity helps students to visualize regulation and relate this regulation to the lac operon system. Highly recommended for AP Biology. This activity allows the gene regulation concept to be presented in a more inquiry fashion.
Students will transform E. They will hypothesis why the cells did not glow and use PCR B to test their hypothesis. After the PCR the students will learn the regulation of this gene, and will induce the promoter to express the product.
In this lab investigation students will learn about a technique called polymerase chain reaction PCR that allows us to examine a very small piece of DNA. This gene codes for the GFP protein, an protein normally produced by jellyfish that is transformed into bacteria in a plasmid pGLO.
This activity lends itself to be conducted inquiry style.In the links you can find the lab results of the protein product and the test date is indicated below each link. In the ranking list below you can see the difference in protein % from all the independent tested whey protein (and casein) shakes.
Lab 3. Protein Determination 10/5/06 Using the Biuret Assay to determine protein concentration in an unknown sample requires, as a preliminary, construction of a standard curve made by assaying a series of protein solutions with known concentration. THE INDICES (MCV & MCHC) These give information regarding the type of anemia, if present.
They indicate if the anemia is due to B12, folic acid, iron, B6, zinc or . Lab reports. All lab reports share certain standard features, regardless of the test(s) they show.
A Federal law, the Clinical Laboratory Improvement Act, regulates all aspects of clinical laboratory testing.
Product Reports. Skip to the Lab Analysis Summary. There are three distinctly different types of silver that are labeled and sold on the market as “colloidal silver”; they are ionic silver, silver protein, and true colloidal silver.
Consumers seeking true colloidal silver are often at a disadvantage because each of these products represents themselves as colloidal silver. Note: This protein report features a fully updated protein content assessment.
Protein content is typically quantified by measuring levels of total nitrogen, which is supplied by bound protein, individual amino acids, and other nitrogenous substances typically found in protein supplements, including creatine.
